An ongoing investigation of a Berkeley, California, high school safety officer resulted in an arrest earlier this week, the Berkeley Patch reports. William Arthur Keys Jr., of Oakland, was charged with identity theft - although the specifics of his crime are currently unknown. Identity theft carries a bail of $10,000. Keys, a graduate of Berkeley High School, worked at the school for 10 years, and has been "instrumental" in creating new policies to handle gun control following multiple incidents that occurred last year, Berkeleyside reports. "In an attempt to head off speculation and to be out in front of any rumors, I want to inform you of a very difficult development that has occurred within the Berkeley High School Community," wrote principal Pasquale Scuderi in a letter to students, as quoted by the news source. "BHS will continue to hold the highest expectations for all of its staff and students and place no one above consequences if and when their actions jeopardize the integrity or security of our school." Keys has been placed on administrative leave as the school district looks further into the alleged crime.
